A: When the welder is in operation, the red fault indicator light indicates an abnormality. The welder can only resume normal operation after troubleshooting. Common causes include abnormal input voltage and welder overheating. If this occurs when the welder has been operating at high current for a long time, shut it down immediately. Restart after the temperature drops. If it still fails to work properly, conduct a detailed inspection of the main circuit and other components.
